To all whom it, may concern.-

ile it knownh that I, CHARLES MANKEDICK, a citizen of the United States, residing at Sullivan, in the county of Sullivan and State of Indiana, have invented certain new and useflil Improvements in Reinforced Concrete Structures, of which the following is a. specification.

My invention relates to certain new and useful im v provemcnts in reinforced concretestructures.

The object of my invention is to produce a'structure l i0 of great tensile and compressive' strength, which shall claims'.

Referring to the drawings wherein the same part is designated by the same reference numeml wherever it occurs, Figure l is a si de clevution of a wall in the course of construction. Fig. 2 is a perspective view showing the method by which the reinforced structure is united together.

l designates a serios of rods which may be of any ,desired size, and arranged either vertically or horizon-` tally in the structure as muy be desired. These rods may be formed of iron, steel or other suitable metal.

2 designates the wires which form the mesh between the rods i. 'ihso wires as seen entend from one rod to the udjuccni rod und encircle the rods alternately. Preferably, und as shown, the wires 2 are turned upon theulsclvcshso es to form eyes 3 around the rods.

Around this structure composed of the rods 1 and the mesh formed hy the Wires 2 Ilnold concroteA in any ordinary or desired manner.

1n Fig. i l have shown the construction as used in a such for instance as a iioor. lt is to bc understood however that my' structure is equally well adopted for use in constructing arches, girders, chimneys or other structures inwhich reinforced concrete muy be found useful.

ln building u wail in accordance with myinvention I preferably have the wire mesh formed into zigzag strips with loops at eachnngle of the zigzag through which' the rods I may be passed. I then place a rod in position with the mesh thereon, and to the other side oi the mesh ttttzichhooks 5 which are loosely mounted upon n rod G byincans of the eyes 7 formed in the hooks.

One of these hopks is hooked within the loop of each angle of the mesh, and by suitably supporting the rod 8 as by their ends the meshis held in position. The sides. of the mold are then plced around the mesh and concretetamped in to a depth s as to leave the eyes of the mesh exposed. The hooks 5 are now removed from the mesh and a. second line of mesh is placed in position and another `rod 1 inserted through the eyes of this second mesh and the projecting eyes of the first mesh. The hooks 5 are then secured to the eyes on the other sides of the second mesh, the molds replaced and concrete. again tamped in as before. If it is not convenient to support the rod 6 at its .ends as above suggested, the same may be supported by a suitable hook 8 which can be attached to anyv convenient supporting device.

The structure is of simple form and is economical to build and can be used in any form of structure where l reinforced construction is desired.

While I have described what I believe to be the' preferred form of my invention, I desire to have it understood that many changes may be made in the form, construction and arrangement oi parts without departing from thel spirit ,oi my invention.

What I claim as new and desire to secure by Letters Patent is '.1. The method Aoi.' building reinforced concrete structures which consistaih'supporting a wirebent into zigzag form,

and moldingconcrete around tpe body of the same,`leaving.

the line of angles on one side ot said wire projecting, then connecting; n second wire 'bent into zigzag form by passing a rod through the angles of the embedded second wire,

of the first wire and the major portiony of the second wire, und continuing said operation tili the structure desired is produced.

2. The method of building reinforced concrete structures which consists in supporting a wire bent into zigzag form and having an eye formed at euch bend ot the wire, mold ing concrete around the body ot the saine, leaving the eyes on one side projecting, then connecting a second wire similarly bent by passing a straight rod through the ud- Jae'ent eyes o! the wires, supporting said second' wire in the desired position, molding concrete around the unwire and said. supporting said second wire in the desired. position, molding concrete around tlie uncovered portioncovered eyes of the first wirennd the -rnnjor portion of the l second wire, leaving the eyes on the free edgeof the sec ond wire uncovered, 'and structure desired is produced.' l K v In testimony whereof I unix my signature in presence oi. two witnesses.
